Bitcoin, as the oldest blockchain, is constantly evolving. Since the emergence of the Ordinals protocol, its ecosystem has been rapidly expanding. To further strengthen the Bitcoin ecosystem, the market urgently needs a solution that enables seamless interoperability between Bitcoin and its second-layer network, as well as with other blockchain ecosystems such as Ethereum. interoperability.

To address this need for interoperability,Polyhedra Networklaunched based onzkBridgeThe Bitcoin cross-chain message transfer protocol. This innovative solution expands the capabilities of Bitcoin to interoperate with a variety of blockchain networks, including various first- and second-layer blockchain networks.

The zkBridge interoperability protocol designed and implemented by Polyhedra Network is a trustless and efficient cross-chain solution based on zero-knowledge proof technology. This applies not only within the Bitcoin ecosystem, but also to the interoperability between Bitcoin and other blockchain networks.

Bitcoin cross-chain message transmission protocol based on zkBridge

As the first trustless interoperability protocol between Bitcoin, Ethereum and other networks, zkBridge is working with developers to apply it to various infrastructures in the Bitcoin ecosystem, Bitcoin second-layer networks, wallets, DeFi protocols and tools.

The zkBridge interoperability protocol will help the Bitcoin ecosystem reach more crypto users safely and efficiently. Assets will no longer be limited to the Bitcoin network or a single other blockchain network. Developers can focus on building the project without worrying about connecting Bitcoin to other chains. zkBridge simplifies the complexity surrounding wallets and accounts, allowing developers to focus on delivering a superior user experience. zkBridge is based on zero-knowledge proof technology to achieve safe and efficient cross-chain interoperability without relying on trust in any third party.

With zkBridge, the Bitcoin network can now securely transmit its current and historical data to over 20 blockchain networks, including Bitcoin Layer 2, Ethereum, and Ethereum Layer 2. The protocol is also compatible with emerging assets in the Bitcoin network, such as Ordinals, BRC-20, and Atomics, and enables trustless access to smart contracts on other blockchain networks, such as Ethereum and Bitcoin Layer 2. Bitcoin data and protocols carry out various calculation logic, and their security is guaranteed by zero-knowledge proof technology.

Additionally, when users want to securely send messages to Bitcoin from another blockchain or transfer assets across chains, Bitcoin’s lack of smart contracts needs to be overcome. zkBridges solution introduces a proof-of-stake mechanism, where verifiers can pledge tokens on the sending chain and are thereby authorized to write data on the Bitcoin network to ensure secure cross-chain transactions; by integrating with infrastructure such as EigenLayer and Babylon, And introduces a cleverly constructed slashing mechanism to further enhance the security of the system through cryptographic economic security.

Building the largest Bitcoin interoperable ecosystem based on zkBridge

Currently, the encryption industry is in the early stages of the development and expansion of the Bitcoin ecosystem. Building an efficient and secure Bitcoin interoperability protocol through zkBridge can fully support the builders of the Bitcoin ecosystem.

Polyhedra Network has partnered with key builders within the Bitcoin ecosystem, covering infrastructure, wallets, Bitcoin second layers, DeFi and tools.
